Improvement in communicating reciprocating motion to pumps



UNITED STATES PATENT OFFICE.

ISAAC VAN OLINDA, OF BROOKLYN, NEWT YORK.

Specification forming part of Letters Patent No. 58,915, dated October 1li, 1866; antedated October 5, i866.

To all whom it may concern:

Be it known that I, IsAAc VAN OLINDA, of the city, county, and State ot' New York, have invented a new and Improved Method of Communicating Reciprocating Motion to Pump-Pistons, Ste.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part ot| this speeilication, in which- Figure 1 is a side elevation. Fig. 2 is a horizontal transverse section taken in the line a of Fig. 1.

Similar letters of reference indicate correspondin g parts in both figures.

This invention relates to that class of pumps in which the piston-rod is made hollow, to serve as the discharge-pipe when the pump is in operation; and it consists in a novel arrange ment of parts for working the said piston-rod, by which it is caused to reciprocate in astraight line instead of heilig bent or turned aside during its stroke by the arc described by the end of the operating-lever with which it is connected.

To enable others skilled in the art to understand the construction and operation of my invention, I will proceed to describe it with ret'- erence to the drawings.

A is the body or cylinder of the pump, the internal parts ot' which may be of any ordinary construction. B is the hollow piston-rod, the upper end of which projects upward through a suitable stufiing-box into a fixed pipe, C, the use of which is to receive and conduct upward the water from the hollow piston-rod, and thus obviate the necessity of extending the said rod the entire height to which it is desired to elevate the water or other fluid.

D is the frame that supports the working parts of the apparatus, and is furnished with a short upright standard, a, in the upper end of which is pivoted the operatinglever E.

r is a collar, the sides of which are flat, and which is rmly secured to the piston-rod B by means of a set-screw, a. The lower or short arm, f, of the lever E is bent at an angle to the upper or long arm of the saine, and is forked or divided into two branches, b, at its outer end each branch b extending past one et the flat sides of the block r; or, in other words, the forked end ot' the short arm j is made to embrace the collar r. Each branch b is furnished with a longitudinal slot, on, which may be curved somewhat, if desired, as represented in Fig. 1.

Close to the outer side ot' cach branch b is a vertical standard, I, which is provided with a vertical slot, h, somewhat greater in length than the stroke of the piston-rod B and exactly in line therewith.

At each side ot' the piston B is a pin, d, which passes through the slot hy of the standards I, and also through the slots `m` in the arms b, and is screwed into the block r. By this means the forked short arm of the lever E is connected with the piston B and thc guidin g-standards I.

A friction-roller, i, is placed upon each pin d where it passes through the slot h of the said standard. By moving the lever E to and t'ro a reciprocating motion is communicated to the piston B, the slots h., with which it is connected by the pins d, and their friction-rollers i, supporting it against any side pressure exerted hy the operating-levcr, and thus causing it to move uniformly in a straight or perpendicular line, while the slots m in the forked arm of the lever E allow the said lever to turn upon its-pivot and the short arm f to describe the proper are in operating the piston-rod, as just set forth.

WVhat I claim as new, and desire to secure by Letters Patent, is

The forked and slotted arm f of the lever E and the slotted vertical guiding-standards I, applied in combination with each other and with the collar r, pins (I, and friction-rollers i', substantially as herein set forth.

I. VAN OLINDA.
